THROTTLE-VALVE FOR CONTROLLING LOCOMOTlVE-BLOWERS.

SPECIFICATION forming part of Letters Patent No. 609,830, dated August 30, 1898. Application filed April 20,1897. serial No. 632,959. (No model.) Patented in Austria January 21,1897, NOAH/208- To all whom it may concern.-

Be it known that I, ANTON PAILA, a subject of the King of Austria-Hungary, residing at.

vention; and Fig. 2 is a transverse sectionalvieW of part of a boiler, showing my improvements.

For the purpose of obtaining smoke abatement even during the stoppage of locomotives and ships I place under the valve P of the regulator R a steam-inlet O in such a way that this is opened and steam let into the pipes r r when the steam-inlet closes, and if the valve P slides down, so as to open the inlet of B, it covers the inlet of O, as shown by Figs. 1 and 2. g is a steam-jet in the chimney of the boiler. In case of a complete stoppagei. e., when no steam is needed-the steam-outlet in the conduit 0" r is stopped by turning the cock it).

What I claim is In combination with a steam boiler, the smoke passage or stack, the regulator R, the steam-conduit 0 opening adjacent thereto and having pipe connection with the smokestack to supply steam thereto and a valve to control the regulator R and the conduit 0 to open the latter when the former is closed, the edges of the openings of the conduit and regulator being in the same plane and the valve being arranged to slide across the same substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
